Salve,
ho installato ex-novo (previa fomattazione) Windows Xp sp2, per motivi di "pulizia"; ormai era piantato. Tutto procede secondo l'iter e va a buon fine.
I problemi arrivano in fase di aggiornamento; "Aggiornamenti automatici" non funziona, allora ho provato ad usare "Windows Update", ma non c'è verso agganciarsi ai server Microsoft, neanche digitando l'indirizzo manualmente nè con IE né con Firefox; mi blocca sempre l'accesso, dandomi il classico messaggio: "Impossibile visualizzare la pagina". Il firewall è disattivato e non ho ancora l'antivirus; mi collego con un router Netgear Dg834g, già settato.
La connessione è attiva e funzionante, solo che non riesce a collegarsi con siti che abbiano a che fare con la Microsoft. Di fatto, adesso mi trovo un sistema operativo nuovo ma completamente privo di aggiornamenti, quindi molto vulnerabile.
Menonomale che ho Linux con cui fare praticamente tutto, altrimenti sarebbe stato come fare sesso senza preservativo... rischi a palla! .
Preciso che è tutto originale (l'ho pagato all'acquisto del pc, ormai nel lontano novembre 2004); mi ha sempre funzionato bene, dopo ogni formattazione. Non capisco perché faccia così.
Grazie .

..... dopo cbbusto ..... prova questo senza toccare niente .... poi spegni e riaccendi ..... ciao e buon lavoro

Provo a postare, sperando che sia una buona idea, il file log di "Windows Update", contenuto nella directory di Windows:

Questo è tutto quello che è successo da quando ho formattato, quindi c'è tutto. Spero possa essere utile.
Grazie davvero!

credo anche io che sia un infezione,puoi provare con un rescue cd di avira,ma visto che hai appena formattato e non hai nulla sul pc io rifarei la procedura.mettiti l installer di un av su una chiavetta,o dove vuoi,la prossima volta,dopodichè PRIMA di connetterti lo installi,e la prima cosa che fai una volta connesso è l aggiornamento dell antivirus.
